This is how I have been spending my "lockdown afternoons" of early 2021 - advancing my CNC project!
It's an aluminium-based-construction milling machine / router with working area of 320x220x120mm in 540x500x540mm enclosure - purposed for precision parts making & prototyping. Project is ongoing.
Initial requirements were as such:
- min. work envelope: 300x200x100mm,
- max. dimensions: 500x500x500mm,
- 230V 1-phase (I am in Europe),
- some capacity to slowly mill non-ferritic metals,
- precision (quality parts) but reasonable costs and possibility to DIY at home,
- full enclosure including electronics inside + elegance.
Finally the work envelope turned out to be 320x220x120mm and dimensions 540x500x540mm. I used:
- HIWIN linear guides,
- ISEL ballscrews, nut and bearing blocks,
- GMT 0,8kW 24000rpm spindle,
- 1,8Nm NEMA24 motors (3A).

All critical comments are welcome.
